Shy and earnest college student Renka (21) is scouted on the street under the pretense of being a gravure shoot. Pretending to be stupid, she is given toys as gifts and asked embarrassing questions, but she is weak to pressure and responds to the men's requests despite her shyness. She is made to change into risqué underwear and is tricked again into thinking it's "just a massage," but she gradually becomes aroused! Although she is confused at first, she eventually opens up and becomes absorbed in masturbating with an ecstatic look on her face!
